The organic solid waste treated by HPS technology in this project contains a large amount of cellulose, starch, higher fatty acid wastes, and there are also plastic substances that are difficult to degrade. This project uses methods to improve the efficient treatment of industrial organic pollutants (supercritical hydrolysis treatment technology) and developed subcritical hydrolysis treatment technology. This technology is currently the latest organic solid waste treatment technology. The treatment of organic solid waste can achieve zero pollution, zero emission, resource utilization, harmlessness, efficiency, economy, green and environmental protection, and is in line with Shanghai and the country's policies and guidance. Subcritical water refers to compressed liquid water with a temperature between 180℃ and 350 ℃. The [H3O +] and [OH-] in subcritical water are close to weak acid or weak base, so they have acid catalysis and base catalysis functions; subcritical water has a sufficiently small dielectric constant and can simultaneously dissolve organic and inorganic substances; At the same time, subcritical water also has the advantages of excellent mass transfer performance and green environmental protection. Subcritical water technology can be used to decompose cellulose, starch, higher fatty acids, and some plastic substances in organic solid waste, transforming macromolecular substances into other organic products such as small molecule lower fatty acids and oligosaccharides. After obtaining high-efficiency organic fertilizers, HPS microbial inoculants (fertilizers) are obtained by further using high-tech technical means to add bacteria with special effects. The subcritical hydrolysis technology (referred to as HPS technology) used in this project is the core treatment of organic waste, and the anaerobic fermentation process is used as an auxiliary measure. The generated biogas provides energy for the core equipment in the subcritical hydrolysis treatment process. Therefore, the project belongs to 07 Resources and Environment, 073 Solid Waste Treatment and Comprehensive Utilization Technology, and 07303 Organic Solid Waste Treatment and Resource Utilization Technology (Applicable Technology for Small Town Waste Treatment) in "Technical Field". A large amount of organic waste is generated in daily life in cities and towns, and agricultural production and product consumption generate a large amount of organic waste. Based on the current situation of agricultural development at home and abroad and the future development trend of fertilizers, this project draws on the advanced achievements of decades of development of microbial 4 fertilizers in my country., using HPS with international leading level (i.e. organic solid waste hydrolysis treatment and resource recycling device) The process treatment system quickly processes organic waste, processes and produces it into high-power shrinkable small molecule nutrient solids and liquid fertilizers, and develops and produces HPS microbial inoculants (Huanken microbial fertilizer) by adding independently developed high-efficiency active functional strains. Key technological innovation points: HPS method has internationally advanced technology for treating organic waste. Subcritical water refers to compressed liquid water with a temperature between 180 ° C and 350 ° C. Subcritical water technology can be used to decompose cellulose, lignin, starch, oils, organic toxic substances and some plastics in garbage., degrade macromolecular substances into organic substances such as small molecule fatty acids, proteins, amino acids, polypeptides and oligosaccharides that are easily absorbed and utilized by crops. The core equipment of this technology has independent intellectual property rights-subcritical hydrolysis treatment of urban and rural organic solid waste to produce organic fertilizers and equipment (obtained the national invention patent certificate on September 18, 2013). The core strain of this project has obtained 2 independent intellectual property rights-a rice endophytic nitrogen-fixing bacterium that improves crop disease and stress resistance and its use (obtained the national invention patent certificate on August 21, 2013); A nitrogen-fixing bacterium that antagonizes Sclerotinia sclerotiorum and its use (obtained the national invention patent certificate on December 25, 2013).
